Subject: Color Mixing (Pigment) question
Our physics book (h.s.) had a question about what color is obtained when
pure green and pure blue pigment are mixed. The book answer was "cyan
pigment." Can someone explain this please?
Why is the result not black? The blue pigment filters out red & green
light and the green pigment filters out blue & red light, so why isn't
the result black?
